Abstract
An energy conversion system is provided including an annular member disposed around a shaft and at least partially defining a first radial flow passage that is fluidly coupled to a wave chamber and a second radial flow passage that is fluidly coupled to a port. A first plurality of nozzle vanes may extend at least partially through the first radial flow passage and may be configured to impart a first exit swirl angle in a fluid. A second plurality of nozzle vanes may extend at least partially through the second radial flow passage and may be configured to impart a second exit swirl angle in the fluid. A turbine wheel may be coupled to the shaft and disposed radially between the shaft and the annular member. The turbine wheel may define an axial flow passage fluidly coupled to the first and second radial flow passages and may include impulse blades.
